Description

本発明は、化学蓄熱反応器、および、化学蓄熱装置に関する。 The present invention relates to a chemical heat storage reactor and a chemical heat storage device.

従来、反応媒体との化学反応によって放熱と蓄熱とを繰り返すことが可能な蓄熱体を備える化学蓄熱反応器が知られている。例えば、特許文献１には、化学蓄熱材を充填されている反応部と、蓄熱時には凝縮熱による高温流体を発生し、放熱時には蒸発潜熱による低温流体を発生する蒸発凝縮部との間の流体のやり取りによって、蓄熱と放熱とを繰り返す技術が開示されている。 Conventionally, a chemical heat storage reactor including a heat storage body capable of repeating heat dissipation and heat storage by a chemical reaction with a reaction medium is known. For example, Patent Document 1 describes a fluid between a reaction portion filled with a chemical heat storage material and an evaporation condensing portion that generates a high-temperature fluid due to heat of condensation during heat storage and a low-temperature fluid due to latent heat of vaporization during heat dissipation. A technique of repeating heat storage and heat dissipation through exchange is disclosed.

しかしながら、特許文献１に記載の化学蓄熱装置では、反応部と蒸発凝縮部とが別々に設けられている。このため、反応部と蒸発凝縮器とを接続し、流体が流れるパイプが設けられているため、化学蓄熱装置の体格が大きくなるおそれがある。 However, in the chemical heat storage device described in Patent Document 1, a reaction section and an evaporation condensing section are separately provided. For this reason, since the reaction unit and the evaporation condenser are connected and a pipe through which the fluid flows is provided, the physique of the chemical heat storage device may become large.

本発明は、上述した課題を解決するためになされたものであり、化学蓄熱反応器において、体格を小さくするとともに重量を軽くする技術を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a technique for reducing the physique and weight of a chemical heat storage reactor.

本発明は、上述の課題の少なくとも一部を解決するためになされたものであり、以下の形態として実現することが可能である。 The present invention has been made to solve at least a part of the above-mentioned problems, and can be realized as the following forms.

（１）本発明の一形態によれば、化学蓄熱反応器が提供される。この化学蓄熱反応器は、水を加熱して蒸気を生成する筒状の第１の蓄熱材と、前記第１の蓄熱材の内側に配置される筒状の内側拘束部材であって、前記内側拘束部材の内側を流れる水が前記第１の蓄熱材に移動可能な孔が形成されている前記内側拘束部材と、前記第１の蓄熱材の外側に配置される筒状の外側拘束部材であって、前記第１の蓄熱材で生成される蒸気が通過可能な孔が形成されている前記外側拘束部材と、前記外側拘束部材の外側に配置され、前記第１の蓄熱材から供給される蒸気によって熱を生成する筒状の第２の蓄熱材とを備える。 (1) According to one embodiment of the present invention, a chemical heat storage reactor is provided. This chemical heat storage reactor is a tubular first heat storage material that heats water to generate steam, and a tubular inner restraint member that is arranged inside the first heat storage material. The inner restraint member in which a hole through which water flowing inside the restraint member can move can move to the first heat storage material is formed, and the tubular outer restraint member is arranged outside the first heat storage material. The outer restraint member having holes through which the steam generated by the first heat storage material can pass, and the steam that is arranged outside the outer restraint member and is supplied from the first heat storage material. It is provided with a tubular second heat storage material that generates heat.

この構成によれば、内側拘束部材の内側を流れる水によって発熱する第１の蓄熱材で生成される蒸気は、外側拘束部材の孔を通って、第１の蓄熱材の外側に配置されている第２の蓄熱材に供給される。蒸気が供給された第２の蓄熱材で生成される熱は、化学蓄熱反応器の外部に放出される。このように、第１の蓄熱材の内側を流れる水から生成される蒸気は、外側拘束部材の孔を通ることによって第１の蓄熱材の外側に配置されている第２の蓄熱材に供給されるため、蒸気を流通させるための蒸気流路を別に形成する部品が不要となる。したがって、化学蓄熱反応器を構成する部品数が少なくなるため、体格が小さくなるとともに、重量を軽くすることができる。
また、水は、第１の蓄熱材から見て第２の蓄熱材の反対側にしか流れないため、第２の蓄熱材に水がかかることを抑制することができる。これにより、水がかかることによって第２の蓄熱材の温度が低下することを抑制し、比較的高温を出力することができる。 According to this configuration, the steam generated by the first heat storage material generated by the water flowing inside the inner restraint member is arranged outside the first heat storage material through the holes of the outer restraint member. It is supplied to the second heat storage material. The heat generated by the second heat storage material supplied with steam is released to the outside of the chemical heat storage reactor. In this way, the steam generated from the water flowing inside the first heat storage material is supplied to the second heat storage material arranged outside the first heat storage material by passing through the holes of the outer restraint member. Therefore, there is no need for a component that separately forms a steam flow path for circulating steam. Therefore, since the number of parts constituting the chemical heat storage reactor is reduced, the physique can be reduced and the weight can be reduced.
Further, since water flows only on the opposite side of the second heat storage material when viewed from the first heat storage material, it is possible to prevent the second heat storage material from being splashed with water. As a result, it is possible to suppress the temperature of the second heat storage material from dropping due to the application of water, and to output a relatively high temperature.

（２）上記形態の化学蓄熱反応器において、前記第１の蓄熱材の体積は、前記第２の蓄熱材の体積より小さくてもよい。
この構成によれば、第１の蓄熱材を、蒸気を生成するために必要十分な量の蓄熱材とすることができる。これにより、化学蓄熱反応器で熱を生成するために不要な蓄熱材を用いてなくてもよいため、化学蓄熱反応器の体格を小さくしかつ重量を軽くすることができる。
また、同じ体格の化学蓄熱反応器と比較した場合、外部に放熱するための第２の蓄熱材の量を増やすことができるため、発熱量を増加させることができる。これにより、さらに高温を出力することができる。 (2) In the chemical heat storage reactor of the above embodiment, the volume of the first heat storage material may be smaller than the volume of the second heat storage material.
According to this configuration, the first heat storage material can be a heat storage material in an amount necessary and sufficient for generating steam. As a result, it is not necessary to use an unnecessary heat storage material to generate heat in the chemical heat storage reactor, so that the physique and weight of the chemical heat storage reactor can be reduced.
Further, when compared with a chemical heat storage reactor having the same physique, the amount of the second heat storage material for dissipating heat to the outside can be increased, so that the amount of heat generated can be increased. As a result, even higher temperatures can be output.

（３）上記形態の化学蓄熱反応器において、前記第１の蓄熱材と前記第２の蓄熱材とは、同じ材料から形成されており、前記第１の蓄熱材の密度は、前記第２の蓄熱材の密度より小さくてもよい。
この構成によれば、第１の蓄熱材が水を加熱して蒸気を生成するときの膨張を抑制することができる。これにより、第１の蓄熱材の変形を小さくすることができるとともに、蒸気拡散が速くなり、第２の蓄熱材に蒸気を迅速に供給することができる。 (3) In the chemical heat storage reactor of the above embodiment, the first heat storage material and the second heat storage material are formed of the same material, and the density of the first heat storage material is the second. It may be lower than the density of the heat storage material.
According to this configuration, expansion when the first heat storage material heats water to generate steam can be suppressed. As a result, the deformation of the first heat storage material can be reduced, the vapor diffusion becomes faster, and steam can be quickly supplied to the second heat storage material.

（４）上記形態の化学蓄熱反応器において、前記第１の蓄熱材と前記第２の蓄熱材とは、異なる材料から形成されており、前記第１の蓄熱材は、熱の発生を開始する温度が、前記第２の蓄熱材が熱の発生を開始する温度より低くてもよい。
この構成によれば、化学蓄熱反応器において第２の蓄熱材より内側に配置されている第１の蓄熱材に伝わる温度が低くても、第１の蓄熱材は蒸気を放出し蓄熱することができる。これにより、蓄熱に必要な時間を短くすることができる。 (4) In the chemical heat storage reactor of the above embodiment, the first heat storage material and the second heat storage material are formed of different materials, and the first heat storage material starts to generate heat. The temperature may be lower than the temperature at which the second heat storage material starts to generate heat.
According to this configuration, even if the temperature transmitted to the first heat storage material arranged inside the second heat storage material in the chemical heat storage reactor is low, the first heat storage material can release steam and store heat. it can. As a result, the time required for heat storage can be shortened.

（５）上記形態の化学蓄熱反応器において、前記外側拘束部材は、筒状の第１の拘束部材と、前記第１の拘束部材の外側に配置される筒状の第２の拘束部材とを有し、前記第１の拘束部材と前記第２の拘束部材との間には、前記第１の蓄熱材が生成した蒸気が流通可能な隙間が形成されてもよい。
この構成によれば、第１の蓄熱材によって生成された蒸気は、第１の拘束部材と第２の拘束部材との間に形成される隙間を通って、第２の蓄熱材の内側全面に拡散することができる。これにより、第２の蓄熱材では、全域において蒸気によって熱を生成することができるため、化学蓄熱反応器の全体から均一に放熱することができる。 (5) In the chemical heat storage reactor of the above-described embodiment, the outer restraint member includes a tubular first restraint member and a tubular second restraint member arranged outside the first restraint member. A gap may be formed between the first restraining member and the second restraining member through which the steam generated by the first heat storage material can flow.
According to this configuration, the steam generated by the first heat storage material passes through the gap formed between the first restraint member and the second restraint member and covers the entire inner surface of the second heat storage material. Can spread. As a result, in the second heat storage material, heat can be generated by steam in the entire area, so that heat can be uniformly dissipated from the entire chemical heat storage reactor.

（６）上記形態の化学蓄熱反応器において、前記外側拘束部材は、前記第１の拘束部材と前記第２の拘束部材を連結する連結部材を有してもよい。
この構成によれば、第１の拘束部材と第２の拘束部材との間の熱のやり取りを連結部材によって行うことができる。これにより、化学蓄熱反応器内部の熱抵抗を小さくすることができるため、応答性に優れた化学蓄熱反応器とすることができる。 (6) In the chemical heat storage reactor of the above embodiment, the outer restraining member may have a connecting member for connecting the first restraining member and the second restraining member.
According to this configuration, heat can be exchanged between the first restraining member and the second restraining member by the connecting member. As a result, the thermal resistance inside the chemical heat storage reactor can be reduced, so that the chemical heat storage reactor with excellent responsiveness can be obtained.

（７）上記形態の化学蓄熱反応器において、前記第２の蓄熱材は、軸心方向の長さが、軸心に対して垂直な方向の長さより長くなるように形成されていてもよい。
この構成によれば、第２の蓄熱材の放熱面を比較的大きくすることができるため、放熱量が比較的大きい化学蓄熱反応器とすることができる。 (7) In the chemical heat storage reactor of the above-described embodiment, the second heat storage material may be formed so that the length in the axial direction is longer than the length in the direction perpendicular to the axial center.
According to this configuration, the heat dissipation surface of the second heat storage material can be made relatively large, so that the chemical heat storage reactor can have a relatively large amount of heat dissipation.

（８）本発明の別の形態によれば、化学蓄熱装置が提供される。この化学蓄熱装置は、上記形態の化学蓄熱反応器と、前記第１の内側拘束部材の内側に水を供給する水タンクと、を備える。この構成によれば、内側拘束部材の内側に供給される水は、内側拘束部材の孔を通って、第１の蓄熱材に供給される。水が供給された第１蓄熱材で生成された蒸気は、外側拘束部材の孔を通って、第２の蓄熱材に供給される。第２の蓄熱材では、供給された蒸気によって化学蓄熱反応器の外部に放出する熱を生成する。これにより、蒸気を流通させるための蒸気流路を別に形成する構成が不要となるため、化学蓄熱装置が体格を小さくなるとともに、重量を軽くすることができる。 (8) According to another embodiment of the present invention, a chemical heat storage device is provided. This chemical heat storage device includes the chemical heat storage reactor of the above-described embodiment and a water tank for supplying water to the inside of the first inner restraint member. According to this configuration, the water supplied to the inside of the inner restraint member is supplied to the first heat storage material through the holes of the inner restraint member. The steam generated by the first heat storage material to which water is supplied is supplied to the second heat storage material through the holes of the outer restraint member. In the second heat storage material, the supplied steam generates heat to be released to the outside of the chemical heat storage reactor. As a result, it is not necessary to separately form a steam flow path for circulating steam, so that the chemical heat storage device can be made smaller in size and lighter in weight.

It is a member that regulates expansion to the outside. A plurality of holes 22b through which steam can pass are formed in the outer wall of the first outer restraint member 22 (see FIG. 2B). In this embodiment, the holes 22b are evenly formed on the outer wall of the first outer restraint member 22.

次に、本実施形態の化学蓄熱装置５の作用について説明する。
本実施形態の化学蓄熱装置５が放熱するとき、バルブ９を開くと、水タンク７内の液体状の水が、接続管８と孔３１ｃを通って、内側拘束部材２１の流路２１ａに供給される。流路２１ａに供給された液体状の水は、内側拘束部材２１の孔２１ｂを通って（図３の直線ハッチの矢印Ｆ１１）、第１の蓄熱材１１に供給される。液体状の水が供給された第１の蓄熱材１１は熱を生成するため、第１の蓄熱材１１に供給された液体状の水の一部は、蒸気となる。蒸気は、第１の外側拘束部材２２の孔２２ｂを通って（図３のドットハッチの矢印Ｆ１２）、第２の蓄熱材１２に供給される。蒸気が供給された第２の蓄熱材１２では、熱が発生する。第２の蓄熱材１２で発生する熱は、反応容器３１を介して、化学蓄熱反応器１Ａの外部に放出される（図３の点線矢印Ｆ１３）。 Next, the operation of the chemical heat storage device 5 of the present embodiment will be described.
When the valve 9 is opened when the chemical heat storage device 5 of the present embodiment dissipates heat, the liquid water in the water tank 7 is supplied to the flow path 21a of the inner restraint member 21 through the connecting pipe 8 and the hole 31c. Will be done. The liquid water supplied to the flow path 21a is supplied to the first heat storage material 11 through the hole 21b of the inner restraint member 21 (arrow F11 of the straight hatch in FIG. 3). Since the first heat storage material 11 to which the liquid water is supplied generates heat, a part of the liquid water supplied to the first heat storage material 11 becomes vapor. The steam is supplied to the second heat storage material 12 through the hole 22b of the first outer restraint member 22 (arrow F12 of the dot hatch in FIG. 3). Heat is generated in the second heat storage material 12 to which steam is supplied. The heat generated by the second heat storage material 12 is released to the outside of the chemical heat storage reactor 1A via the reaction vessel 31 (dotted line arrow F13 in FIG. 3).

以上説明した、本実施形態の化学蓄熱反応器１Ａによれば、内側拘束部材２１の流路２１ａを流れる水によって発熱する第１の蓄熱材１１で生成される蒸気は、第１の外側拘束部材２２の孔２２ｂを通って、第１の蓄熱材１１の外側に配置されている第２の蓄熱材１２に供給される。蒸気が供給された第２の蓄熱材１２で生成される熱は、化学蓄熱反応器１Ａの外部に放出される。このように、第１の蓄熱材１１の内側を流れる水から生成される蒸気は、第１の外側拘束部材２２の孔２２ｂを通ることによって第１の蓄熱材１１の外側に配置されている第２の蓄熱材１２に供給されるため、蒸気を流通させるための蒸気流路を別に形成する部品が不要となる。したがって、化学蓄熱反応器１Ａを構成する部品数が少なくなるため、体格が小さくなるとともに、重量を軽くすることができる。 According to the chemical heat storage reactor 1A of the present embodiment described above, the steam generated by the first heat storage material 11 generated by the water flowing through the flow path 21a of the inner restraint member 21 is the first outer restraint member. It is supplied to the second heat storage material 12 arranged outside the first heat storage material 11 through the hole 22b of the 22. The heat generated by the second heat storage material 12 to which steam is supplied is released to the outside of the chemical heat storage reactor 1A. As described above, the steam generated from the water flowing inside the first heat storage material 11 is arranged outside the first heat storage material 11 by passing through the hole 22b of the first outer restraint member 22. Since it is supplied to the heat storage material 12 of No. 2, a component for separately forming a steam flow path for circulating steam becomes unnecessary. Therefore, since the number of parts constituting the chemical heat storage reactor 1A is reduced, the physique can be reduced and the weight can be reduced.

また、本実施形態の化学蓄熱反応器１Ａによれば、水は、第１の蓄熱材１１から見て第２の蓄熱材１２の反対側にしか流れないため、第２の蓄熱材１２に水がかかることを抑制することができる。これにより、水がかかることによって第２の蓄熱材１２の温度が低下することを抑制し、比較的高温を出力することができる。 Further, according to the chemical heat storage reactor 1A of the present embodiment, water flows only to the opposite side of the second heat storage material 12 when viewed from the first heat storage material 11, so that water flows into the second heat storage material 12. Can be suppressed. As a result, it is possible to suppress a decrease in the temperature of the second heat storage material 12 due to the application of water, and to output a relatively high temperature.

また、本実施形態の化学蓄熱反応器１Ａによれば、第１の蓄熱材１１の体積は、第２の蓄熱材１２の体積より小さい。これにより、第１の蓄熱材１１を、蒸気を生成するために必要十分な量の蓄熱材とすることができる。したがって、化学蓄熱反応器１Ａで熱を生成するために不要な蓄熱材を用いてなくてもよいため、化学蓄熱反応器１Ａの体格を小さくしかつ重量を軽くすることができる。
また、同じ体格の化学蓄熱反応器と比較した場合、外部に放熱するための第２の蓄熱材１２の量を増やすことができるため、発熱量を増加させることができる。これにより、さらに高温を出力することができる。 Further, according to the chemical heat storage reactor 1A of the present embodiment, the volume of the first heat storage material 11 is smaller than the volume of the second heat storage material 12. As a result, the first heat storage material 11 can be used as a heat storage material in an amount necessary and sufficient for generating steam. Therefore, since it is not necessary to use an unnecessary heat storage material to generate heat in the chemical heat storage reactor 1A, the physique and weight of the chemical heat storage reactor 1A can be reduced.
Further, when compared with a chemical heat storage reactor having the same physique, the amount of the second heat storage material 12 for dissipating heat to the outside can be increased, so that the amount of heat generated can be increased. As a result, even higher temperatures can be output.

また、本実施形態の化学蓄熱反応器１Ａによれば、第１の蓄熱材１１と第２の蓄熱材１２が同じ材料から形成されており、第１の蓄熱材１１の密度は、第２の蓄熱材１２の密度より小さい。これにより、第１の蓄熱材１１が水を加熱して蒸気を生成するときの膨張を抑制することができる。したがって、第１の蓄熱材１１の変形を小さくすることができるとともに、蒸気拡散が速くなり、第２の蓄熱材１２に蒸気を迅速に供給することができる。 Further, according to the chemical heat storage reactor 1A of the present embodiment, the first heat storage material 11 and the second heat storage material 12 are formed of the same material, and the density of the first heat storage material 11 is the second. It is smaller than the density of the heat storage material 12. As a result, expansion when the first heat storage material 11 heats water to generate steam can be suppressed. Therefore, the deformation of the first heat storage material 11 can be reduced, the vapor diffusion becomes faster, and steam can be quickly supplied to the second heat storage material 12.

また、本実施形態の化学蓄熱反応器１Ａによれば、第２の蓄熱材１２は、軸心方向の長さが、軸心に対して垂直な方向の長さより長くなるように形成されている。これにより、第２の蓄熱材１２の放熱面を比較的大きくすることができるため、放熱量が比較的大きい化学蓄熱反応器１Ａとすることができる。 Further, according to the chemical heat storage reactor 1A of the present embodiment, the second heat storage material 12 is formed so that the length in the axial direction is longer than the length in the direction perpendicular to the axial center. .. As a result, the heat dissipation surface of the second heat storage material 12 can be made relatively large, so that the chemical heat storage reactor 1A having a relatively large amount of heat dissipation can be obtained.

The heat generated in the second heat storage material 12 to which the steam is supplied is released to the outside of the chemical heat storage reactor 1B via the reaction vessel 31 (dotted arrow F23 in FIG. 5).

以上説明した、本実施形態の化学蓄熱反応器１Ｂによれば、第１の蓄熱材１１によって生成された蒸気は、第１の外側拘束部材２２と第２の外側拘束部材３２との間の隙間３０を通ることによって、第２の蓄熱材１２に対して拡散させることができる。よって、第２の蓄熱材１２の全域に蒸気が供給されやすくなるため、化学蓄熱反応器１Ｂの全体から放熱することができる。 According to the chemical heat storage reactor 1B of the present embodiment described above, the steam generated by the first heat storage material 11 is a gap between the first outer restraint member 22 and the second outer restraint member 32. By passing through 30, it can be diffused to the second heat storage material 12.

＜第１０実施形態＞
図１３は、第１０実施形態の化学蓄熱反応器の断面図である。第１０実施形態の化学蓄熱反応器は、第１実施形態の化学蓄熱反応器（図３）と比較すると、第２の蓄熱材の形状および反応容器の形状が異なる。 <10th Embodiment>
FIG. 13 is a cross-sectional view of the chemical heat storage reactor of the tenth embodiment. The shape of the second heat storage material and the shape of the reaction vessel of the chemical heat storage reactor of the tenth embodiment are different from those of the chemical heat storage reactor of the first embodiment (FIG. 3).

本実施形態の化学蓄熱反応器１Ｊは、図１３に示すように、第１の蓄熱材１１と、第２の蓄熱材７２と、内側拘束部材２１と、第１の外側拘束部材２２と、反応容器８１を備える。 As shown in FIG. 13, the chemical heat storage reactor 1J of the present embodiment reacts with the first heat storage material 11, the second heat storage material 72, the inner restraint member 21, and the first outer restraint member 22. A container 81 is provided.

第２の蓄熱材７２は、軸心方向の長さが、軸心に対して垂直な方向の長さより長くなるように形成されている横断面が星型多角形状の筒状部材である。第２の蓄熱材７２は、最も内径が小さい部分の内径が、第１の外側拘束部材２２の外径より大きくなるように形成されており、内側には、内側拘束部材２１が挿入されている第１の蓄熱材１１と第１の外側拘束部材２２が挿入されている。第２の蓄熱材７２では、第１の蓄熱材１１が生成する蒸気によって水和反応が行われ、熱を生成する。 The second heat storage material 72 is a tubular member having a star-shaped polygonal cross section, which is formed so that the length in the axial direction is longer than the length in the direction perpendicular to the axial center. The second heat storage material 72 is formed so that the inner diameter of the portion having the smallest inner diameter is larger than the outer diameter of the first outer restraint member 22, and the inner restraint member 21 is inserted inside. The first heat storage material 11 and the first outer restraint member 22 are inserted. In the second heat storage material 72, the hydration reaction is carried out by the steam generated by the first heat storage material 11 to generate heat.

反応容器８１は、第２の蓄熱材７２の外側に配置されている横断面が星型多角形状の略筒状の部材である。反応容器８１は、第２の蓄熱材７２の外側を覆うように形成されており、第１の蓄熱材１１と第２の蓄熱材７２を密閉することによって大気との接触を防止するとともに、蒸気との反応による第２の蓄熱材７２の外側への膨張を規制する。 The reaction vessel 81 is a substantially tubular member having a star-shaped polygonal cross section, which is arranged outside the second heat storage material 72.

It regulates the outward expansion of the second heat storage material 72 due to the reaction with.

以上説明した、本実施形態の化学蓄熱反応器１Ｊによれば、第１の蓄熱材１１で生成される蒸気は、第１の外側拘束部材２２の孔２２ｂを通って、第１の蓄熱材１１の外側に配置されている第２の蓄熱材７２に供給されるため、蒸気を流通させるための蒸気流路を別に形成する構成が不要となる。したがって、化学蓄熱反応器１Ｊの体格が小さくなるとともに、重量を軽くすることができる。 According to the chemical heat storage reactor 1J of the present embodiment described above, the steam generated by the first heat storage material 11 passes through the holes 22b of the first outer restraint member 22, and the first heat storage material 11 Since it is supplied to the second heat storage material 72 arranged on the outside of the above, it is not necessary to separately form a steam flow path for circulating steam.

また、本実施形態の化学蓄熱反応器１Ｊによれば、反応容器８１は、横断面が星型多角形状の略筒状の部材であるため、外壁の面積が、横断面が円形状の場合より広くなる。これにより、第２の蓄熱材７２が生成する熱を効率的に放熱することができる。 Further, according to the chemical heat storage reactor 1J of the present embodiment, since the reaction vessel 81 is a substantially tubular member having a star-shaped polygonal cross section, the area of the outer wall is larger than that when the cross section is circular. Become wider. As a result, the heat generated by the second heat storage material 72 can be efficiently dissipated.

＜本実施形態の変形例＞
本発明は上記の実施形態に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能であり、例えば次のような変形も可能である。 <Modified example of this embodiment>
The present invention is not limited to the above-described embodiment, and can be implemented in various aspects without departing from the gist thereof. For example, the following modifications are also possible.

［変形例１］
上述の実施形態では、第２の蓄熱材１２は、体積が、第１の蓄熱材１１の体積より大きく、密度が、第１の蓄熱材１１の密度より大きいとした。また、第２の蓄熱材１２の熱を生成するときの温度は、第１の蓄熱材１１の熱を生成するときの温度より高いとした。しかしながら、第１の蓄熱材１１と第２の蓄熱材１２との関係は、これに限定されない。第１の蓄熱材と第２の蓄熱材とは、同じ体積であってもよいし、同じ密度であってもよい。 [Modification 1]
In the above-described embodiment, the volume of the second heat storage material 12 is larger than the volume of the first heat storage material 11, and the density is larger than the density of the first heat storage material 11. Further, the temperature at which the heat of the second heat storage material 12 is generated is higher than the temperature at which the heat of the first heat storage material 11 is generated. However, the relationship between the first heat storage material 11 and the second heat storage material 12 is not limited to this. The first heat storage material and the second heat storage material may have the same volume or the same density.

［変形例２］
第３実施形態の、第１の外側拘束部材２２と第２の外側拘束部材３２との間に隙間３０を形成する構成は、第５〜１０実施形態に適用されてもよい。これにより、第１の蓄熱材によって生成された蒸気が第２の蓄熱材に対して拡散しやすくなるため、化学蓄熱反応器の全体から放熱することができる。 [Modification 2]
The configuration of the third embodiment in which the gap 30 is formed between the first outer restraint member 22 and the second outer restraint member 32 may be applied to the fifth to tenth embodiments. As a result, the steam generated by the first heat storage material is easily diffused to the second heat storage material, so that heat can be dissipated from the entire chemical heat storage reactor.

［変形例３］
また、第３実施形態の隙間３０を形成する構成を第５〜１０実施形態に適用する場合、第４実施形態の連結部材３３を適用してもよい。これにより、化学蓄熱反応器内部の熱抵抗を小さくすることができるため、応答性に優れた化学蓄熱反応器とすることができる。 [Modification 3]
Further, when the configuration for forming the gap 30 of the third embodiment is applied to the fifth to tenth embodiments, the connecting member 33 of the fourth embodiment may be applied. As a result, the thermal resistance inside the chemical heat storage reactor can be reduced, so that the chemical heat storage reactor with excellent responsiveness can be obtained.

［変形例４］
上述の実施形態では、第１の蓄熱材と第２の蓄熱材とは、同じ材料から形成されているとした。しかしながら、第１の蓄熱材と第２の蓄熱材とは、異なる材料から形成されてもよい。このとき、第１の蓄熱材において水によって熱の生成を開始するときの第１蓄熱材の温度を、第２の蓄熱材において蒸気によって熱の生成を開始するときの第２蓄熱材の温度より低くすると、化学蓄熱反応器において第２の蓄熱材より内側に配置されている第１の蓄熱材に伝わる温度が低くても、第１の蓄熱材は蒸気を放出し蓄熱することができる。これにより、蓄熱に必要な時間を短くすることができる。 [Modification example 4]
In the above-described embodiment, it is assumed that the first heat storage material and the second heat storage material are formed of the same material. However, the first heat storage material and the second heat storage material may be formed from different materials. At this time, the temperature of the first heat storage material when heat generation is started by water in the first heat storage material is higher than the temperature of the second heat storage material when heat generation is started by steam in the second heat storage material. When it is lowered, the first heat storage material can release steam and store heat even if the temperature transmitted to the first heat storage material arranged inside the second heat storage material in the chemical heat storage reactor is low. As a result, the time required for heat storage can be shortened.

［変形例５］
上述の実施形態では、第２の蓄熱材は、軸心方向の長さが、軸心に対して垂直な方向の長さより長くなるように形成されているとした。しかしながら、軸心方向の長さと、軸心に対して垂直な方向の長さとの関係はこれに限定されない。 [Modification 5]
In the above-described embodiment, the second heat storage material is formed so that the length in the axial direction is longer than the length in the direction perpendicular to the axial center. However, the relationship between the length in the axial direction and the length in the direction perpendicular to the axial center is not limited to this.

［変形例６］
上述の実施形態では、第１の蓄熱材１１と第２の蓄熱材１２は、円筒状部材であるとした。しかしながら、第１の蓄熱材１１および第２の蓄熱材１２の形状は、これに限定されない。 [Modification 6]
In the above-described embodiment, the first heat storage material 11 and the second heat storage material 12 are assumed to be cylindrical members. However, the shapes of the first heat storage material 11 and the second heat storage material 12 are not limited to this.

図１４は、第１実施形態の変形例の化学蓄熱反応器１Ａが備える第２の蓄熱材１２の模式図である。図１４に示すように、第２の蓄熱材１２は、半円筒状の部材１２ｂと半円筒状の部材１２ｃとから構成され、２つに分割可能な形状であってもよい。これにより、内側に第１の蓄熱材１１などを挿入しやすくなるだけでなく、蒸気との反応によって膨張しても破損しにくくすることができる。 FIG. 14 is a schematic view of the second heat storage material 12 included in the chemical heat storage reactor 1A of the modified example of the first embodiment. As shown in FIG. 14, the second heat storage material 12 is composed of a semi-cylindrical member 12b and a semi-cylindrical member 12c, and may have a shape that can be divided into two. This not only makes it easier to insert the first heat storage material 11 or the like inside, but also makes it less likely to be damaged even if it expands due to the reaction with steam.

［変形例７］
第１実施形態では、水タンク７に、１つの化学蓄熱反応器１Ａが接続するとした。しっかしながら、水タンク７に接続する化学蓄熱反応器１Ａの数はこれに限定されない。 [Modification 7]
In the first embodiment, one chemical heat storage reactor 1A is connected to the water tank 7. However, the number of chemical heat storage reactors 1A connected to the water tank 7 is not limited to this.

図１５は、第１実施形態の変形例の化学蓄熱装置の模式図である。図１５（ａ）に示すように、２つの化学蓄熱反応器１Ａをそれぞれの軸心方向が略平行となるように並べたものを水タンク７に接続してもよい。この場合、接続管８は、２つの化学蓄熱反応器１Ａのそれぞれの孔３１ｃに接続し、水タンク７の水を同時に２つの化学蓄熱反応器１Ａに供給可能なマニホールド１０を備えることが望ましい。
また、水タンク７に接続する化学蓄熱反応器の数は３本以上であってもよい。 FIG. 15 is a schematic view of a chemical heat storage device of a modified example of the first embodiment. As shown in FIG. 15A, two chemical heat storage reactors 1A may be connected to the water tank 7 by arranging them so that their axial directions are substantially parallel to each other. In this case, it is desirable that the connecting pipe 8 is connected to the respective holes 31c of the two chemical heat storage reactors 1A and includes a manifold 10 capable of simultaneously supplying the water of the water tank 7 to the two chemical heat storage reactors 1A.
Further, the number of chemical heat storage reactors connected to the water tank 7 may be three or more.
